IMPROVEMENT 1N Moss-GOUPLINGS.

ro ALL WHoM 1T MAY ooNoERN:

Be it.known that I, JOHN KEnNs, of the city, county, and Sta-te of New York, have invented a. new and improved Hose-Coupling; and I do hereby declare that the following is u full, clear, and exact description thereof, whiehwill ena-ble others skilled in the ort to make and use the seme, reference being had to the eccompnnyingjdrnwings, forming portV of this specification.

This invention relates to a hose-couplingot` such construction that two pierces of hose can be secured to each other by its use without e wrench, or even without turning :L ring or a nut for the purpose. All that vis required to connect two ends of hose is to hold them together, and-push one towards the other, and the connection will be complete, safe, and strong.

The invention consists in the use of two or more jaws, which are pivoted to the metal tube which forms one part of the` coupling. These jews are provided with hooks nt their ends, and fit over :L projecting ring on the ondof the otherpiece of tube. The jews are pressed toward the tube hy Ineens of springs, and areA spread, when they are to lock the coupling, bythe rounded rim of the opposite tubo coniing in Contact with the rounded edge of the hooks. In the ennexeddruwings my invention is illustrated- V Figure l being a side View of my improved coupling, and

Figure 2 'o .sectional view of the-seme.

Similnr letters of reference indicate corresponding ports.

A represents the tube-on one end otv thezihose, and B the end of the opposite hose. To the former nre hinged two or more jaws a, with hook-shaped ends' b, which engoge the rim c projecting from the end of I3, us

. shown in 2. The jawsare pressed together, or towards the tube, by ineens of an Indio-rubber or other spring, d., p

This device is soli-locking, as when the end of tube B is pressed'agoinst the end ot" tube A, it will spread the jews apart, and the letter will then spring over the `rim c, and thus securely hold the two ends of hose together. For disengaging the two pieces of hose, it will be necessary to drew the jews a apart, for which purpose handles e eare provided on the jews, es is shown in fig. l.

Iy claim as new, and desire to secure by Letters Patent- 1. The combination of the tnbe A, jews a; a, with hooks b l, springscZ/tube B, with shoulders c, :1s and for the purpose specified, i' l 2. The jews et a on the tube A, provided with hooks b b, fitting into a. groove in the tube B, and forced together by a, spring or springs d, arranged between the jaws a a und tube A, as hereinshown and described.
